Why is it so difficult to see the other side's point of view? When ever I get annoyed with my neighbor(s), and I've had some difficult and extended legal battles with them, I try to step back and view the problem from their perspective. Sometimes it changes my mind, and sometimes it doesn't, but it always is a good exercise.
For example, I'll play the role of your neighbor;
I've owned this property for X-years, and the drainage has always concerned me. I may have even mentioned it to my old neighbor, but nothing has ever been resolved. It's a annoyance that's eaten at me for all these years. Now I've got a new young neighbor that wants to put a pool in his yard. I'm convinced that a pool would make things even worse. Damn, I wish there was some way I could prevent his putting in the pool unless the problem was finally resolved and corrected.
Hey, the neighbor just asked me if he could trespass on my property in order to install his pool. This a great opportunity to finally get something done to resolve MY drainage situation. I think I'll tell him my concerns and maybe he'll help me in getting something done about the drainage.
It seems like my new neighbor is unconcerned with my problem and all he can think about is his pool. He is callimg and writing more and more asking that I give him permission, but that doesn't fix my problem, so I guess I'll just ignore him. I'd like to be a nice guy, but he's all about himself and doesn't care about me, so screw him.
